Purpose
The purpose of this study is to develop a decision-support framework that can be used by decision-makers to suspend public infrastructure projects. Additionally, the study also investigates how to select the most convenient infrastructure project for suspension.
Design/methodology/approach
The proposed framework includes an extensive set o...
Despite their promising potential, the level of implementation of smart contracts is not at the desired level. To expedite the acceptance and deployment of smart contracts, the barriers to the implementation of smart contracts should be revealed. Past studies, however, do not provide a comprehensive theoretical basis due to several methodological d...
Purpose
The purpose of this paper is to propose a decision support framework that can be used by decision-makers to identify the most convenient disruption analysis (DA) methods for megaprojects and their stakeholders.
Design/methodology/approach
The framework was initially developed by conducting a comprehensive literature review to obtain extens...
Being prone to dispute, airport projects involve diverse stakeholders including also national and international aviation authorities, and this complicates the dispute resolution process in these projects. Hence, decision-makers should not entirely rely on standard forms of contracts to settle disputes in airport projects. Instead, these projects ne...
The Building Audit system (BAS) has often been criticized due to its various drawbacks by researchers, construction practitioners, and professional chambers. Existing studies, however, do not comprehensively investigate the problems seen in Turkish BAS. Since the decision-makers are provided with little knowledge about the drawbacks of the system,...
This paper aims to develop a roadmap for ISO 9001-certified construction companiesn to move towards effective Total Quality Management (TQM) implementation. Although ISO 9001-certified companies are more ready for TQM implementation, there is no roadmap developed for these companies to move towards TQM. Therefore, in this study, 8 main critical suc...
Changes such as change orders and site instructions resulting in resource diversion and work area congestion negatively affect the crew's productivity and thus a disruption occurs. Diminishing labour productivity ends up with an increase in the costs and time needed to accomplish the work and this jeopardizes the owner's return on investment, concl...
Construction industry is prone to disputes resulting in the Extension of Time (EOT). Numerous studies were conducted to improve delay analysis methods; however, the construction industry still suffers from the dispute stemming from EOT. Unresolved dispute concerning EOT ends up in time and cost overrun in projects as well as deteriorate the relatio...
Purpose
The purpose of this paper is to propose a disruption claim management (DCM) life cycle and a risk management framework to provide comprehensive guidance to construction practitioners for facilitating effective and efficient DCM.
Design/methodology/approach
DCM life cycle was initially developed through a focus group discussion (FGD) with t...
The central purpose of this study is to propose a set of key performance indicators (KPIs) to measure the performance of construction small and medium enterprises (SMEs) that have been ignored in the performance management literature so far. Secondly, this study aims to determine the most crucial KPIs by using the fuzzy VIKOR method to improve cost...
Deconstruction is the eco-friendly alternative to demolition. It can help reduce the waste stream from urban regeneration projects (URPs) to landfills. The literature, however, does not provide a sufficient theoretical basis in terms of life cycle and life cycle risks of deconstruction. This lacking presents a major roadblock to its implementation...
Building information modelling (BIM) has recently become a key to bolster the performance of construction projects. BIM is a virtual platform that all data about all phases of the project, such as maintenance, management, and operation are entered and stored. BIM is preferred for reasons such as data storage, coordinated work among partners, cost e...
Although some studies identified positive effects of ISO certification on company performance, some studies proposed that the ISO 9000 certification does not guarantee high performance. To understand the reasons for performance differences between ISO-certified companies, these two assessments should be examined. In this way, ISO-certified companie...
Construction projects are often deemed as complex and high-risk endeavours, mostly because of their vulnerability to external conditions as well as project-related uncertainties. Risk management (RM) is a critical success factor for companies operating in the construction industry. RM is a knowledge-intensive process that requires effective managem...
Decision-makers face many challenging issues during their careers. To improve the accuracy of decisions they made, Multi-criteria Decision Making (MCDM) plays an important role. One of the widely used MCDM methods is the Analytical hierarchy process (AHP). There are many reasons (advantages) behind the popularity of the AHP. For instance, AHP is th...
The performance of the construction industry has been widely criticized in the literature due to substantial delays and cost overruns. The dynamic, turbulent, and complex environment of the construction industry can lead to poor performance causing occurrence of numerous risks that can adversely affect the performance of the projects. Risk manageme...
Purpose
The purpose of this paper is to develop a new conceptual life cycle performance measurement system (PMS) based on stage level key performance indicators (KPIs) to measure the performance of build–operate–transfer (BOT) projects.
Design/methodology/approach
This study uses a literature review to reveal the deficiencies of existing PMSs for...
Purpose
The purpose of this paper is to identify and prioritize key performance indicators (KPIs) that can be used for stage-based performance assessment of build-operate-transfer (BOT) projects.
Design/methodology/approach
This research was conducted through focus group discussions and face-to-face questionnaires. Firstly, stage-level KPIs for BO...
Although the PPP concept is preferred for delivering mega-infrastructure projects in developed and developing countries in recent years, the success of these projects has been criticized. Especially, in Turkey, there are intensive criticisms about these project’s success concerning economic and environmental aspects. Determining the success criteri...
